Volvo models this fault code applies to
Applies to the following models:
5 modelsS60 (2001–2009), S80 (1999–2006), V70 (2000–2008), V70 XC / XC70 (2001–2007), XC90 (2003–)
What does this fault code mean?
The control module has received too weak a signal from the floor and ventilation damper motor. The damper divides airflow between the floor and the vents, so when the signal is missing the airflow to the floor or the vents can be wrong.
Possible causes
- Signal wire linking the control module to the damper motor shorted to live voltage
- Open circuit in the signal wire linking the control module to the damper motor
- Contact resistance, oxidation or play in the connectors
- Defective damper motor
What you can do
- 1Start the engine, switch on the blower and press the floor and ventilation button. Check that the airflow changes
- 2Check the connector at the floor and defroster damper motor for loose contacts and corrosion
- 3Check the wiring for chafing and crushed areas
- 4Remedy anything found and clear the fault code
- 5If the fault remains, have a workshop check the signal wire and replace the damper motor if needed
- 6If you have a diagnostic tool, follow the damper position in live data while turning the control and check that it changes smoothly
